Unexplained Electric Space Heat

Hi,

I am modeling my design building that contains some AHUs, UHs, CUHs, and MAUs. All of the heating in the systems comes from 3 hot water boilers that supply hot water coils in the air-side equipment. The VAV systems have VAV boxes with hot water reheat coils and there are no electric resistance heating coils in the building. However when I simulate the model I get an extremely large space heating load under the Electric Consumption. Has anyone come across this problem?

Thank you for any ideas or help.

.INP and .PD2 files needs to be looked at. You have SOMETHING set as electric heat.

Stephen,

You might check to see if you have electric baseboard heaters set up on
your air side HVAC under heating, under the preheat/baseboard tab. That
is the main thing that I have often seen on reviews get left mistakenly
on.

DOE2.2, like DOE2.1e allows for the Electric Input Ratio for fossil
boilers. The EIR represents boiler components such as a blower
fan. I can't seem to locate the default for HW-BOILER in equest but
for DOE2.1e the default EIR is 0.022. If you don't override the
default you will see Electric Heat in the results. In the equest
Boiler Properties input screen the Electric Input Ratio is at the
right side of the dialog box.
